How to convert negative number to positive in Java
To convert negative number to positive number (this is called absolute value), uses Math.abs(). This Math.abs()
method is work like this “number = (number < 0 ? -number : number);
".
See a complete example :
package com.mkyong;
public class app{
public static void main(String[] args) {
int total = 1 + 1 + 1 + 1 + (-1);
//output 3
System.out.println("Total : " + total);
int total2 = 1 + 1 + 1 + 1 + Math.abs(-1);
//output 5
System.out.println("Total 2 (absolute value) : " + total2);
}
}
Output
Total : 3
Total 2 (absolute value) : 5
In this case, Math.abs(-1)
will convert the negative number 1 to positive 1.
tell me a program of negative and positive
Class positive
{
void main (int n )
{
if (n>0)
System.out println (n+”is positive “);
else
System.out . println (n+”is negative “);
}
}
shut up bro
Literally just had to write a program to determine if Palindrome or not. 7 years later this was helpful.
time clock like for example calculating employees hours in and out with minutes included and seconds, it should create a negative number, so Math.abs is a really good tool, because it can actually convert the – sign to and absolute value number, plus it saves the programmer time and work.
